Payara Server is compatible with Eclipse MicroProfile and is a Jakarta EE compatible implementation.

What is Payara Platform Enterprise? 

Payara Platform Enterprise is stable, supported software designed for mission critical systems in production and containerized Jakarta EE and MicroProfile applications. 

Payara Server Enterprise is a cloud-native middleware application platform supporting mission critical production systems with reliable and secure deployments of Jakarta EE (Java EE)  applications on premise, in the cloud, or hybrid environments. A stable platform with monthly releases, bug fixes, and a 10-year software lifecycle, Payara Server is aggressively compatible with the ecosystem, cloud vendors, Docker, and Kubernetes. 

Payara Micro Enterprise is the lightweight middleware platform of choice for containerized Jakarta EE (Java EE) microservices deployments.  Less than 70MB, Payara Micro requires no installation, configuration, or code rewrites – so you can build and deploy a fully working app within minutes. Payara Micro Enterprise offers a 10-year software lifecycle, monthly releases, and bug fixes. 

Is support available for the Payara  Platform?

Payara Platform Enterprise is fully supported and stable software for mission critical production environments. If you’re running Payara Server or Payara Micro in production, you should use Payara Enterprise to benefit from greater security, stability, and support. If you’re currently using Payara Platform Community stream as a customer, we recommend switching to Payara Enterprise, but support is available for both Community and Enterprise streams.  

How is the Payara Platform licensed? Do I have to buy a license to run Payara Server or Payara Micro? 

The Payara Platform is open source. You can run Payara Server or Payara Micro Community Editions without buying a license. Payara Platform Community focuses on rapid change and innovation, and provides a place for developers to play with the newest features of Payara Platform as soon as possible – but we can’t guarantee stability. 

For customers using Payara Platform in mission critical or production environments, you should obtain Payara Platform Enterprise for security, stability, and the included support options, which is provided with a EULA license. 

Is Payara Platform Jakarta EE compatible? 

Payara Server Enterprise and Payara Server Community Editions are both Jakarta EE 8 Compatible. 

How do I upgrade to the latest Payara Server Community or Payara Micro Community Edition?

To find out what’s the best way to upgrade your Payara Server check out our Upgrade Guide here.

What’s the difference between Payara Services and Payara Foundation?

Payara Foundation is a not-for-profit organisation that owns and protects Payara Server’s and Payara Micro’s code, trademark and documentation, ensuring the continued development and maintenance of Payara Server as open source software. Payara Services Ltd on the other hand is a private company and a major contributor to the development and engineering effort of the Payara Server open source project and the Payara Foundation.

What is the relationship between Payara Server and GlassFish OpenSource Edition?

Payara Server is derived from the upstream GlassFish source tree with our own enhancements and fixes. Payara and Payara Server are not affiliated with, maintained, authorized, endorsed or sponsored by Oracle or any of its affiliates.

How is Payara Server better than GlassFish?

On top of the regular quarterly releases with bug fixes and patches, Payara Server has a lot of new tools and features that are not present in GlassFish. See our GlassFish vs Payara Server page here for more details and features comparison.

Is it difficult to migrate from GlassFish Open Source Edition 4.1 to Payara Server 4.1?

Absolutely not! Payara Server is derived from GlassFish Server Open Source Edition so the migration is really easy. Check out our GlassFish to Payara Server Migration Guide for some useful tips on migration process. We also created a guide to then migrate from Payara Server 4 to Payara Server 5.

And if you think you might need some help with migration (especially from GlassFish 3 and below), we can also help you with the process if you become a Payara Platform Enterprise customer and choose the available Migration & Project Support option.

Where can I find Payara Server and Payara Micro documentation?

The Payara Server and Payara Micro documentation is available here.

What happened to the three release streams, Community, Features, and Stability? 

In the past, Payara Platform offered three release streams: 

  • Community – quarterly releases containing new features, bug fixes, and patches, available to all Payara Server and Payara Micro users. 
  • Features – monthly patches and fixes added to the regular quarterly releases, available to customers only. 
  • Stability – monthly bug fixes and security patches and no new features for 12 months to boost the stability of production environments, available to customers only. 

The Stability Stream and Features Stream are now combined to form Payara Platform Enterprise. Instead of choosing between the potential instability of the Features stream, or having no features for 12 months in the Stability stream, customers receive the benefits of both with Payara Server Enterprise or Payara Micro Enterprise. Payara Platform Enterprise is designed for stability and security in production environments and new features are added to Payara Platform Enterprise after they have been thoroughly tested for stability in the Community version.  

The Community Stream is now the Payara Platform Community version and features frequent releases to drive innovation. Payara Server Community and Payara Micro Community are dedicated to rapid change and innovation, giving developers a place to play with the latest features of the Payara Platform as soon as possible.  

What happens if I’m a Payara Enterprise customer on the community stream? 

We recommend all customers running Payara Server or Payara Micro in production move to Payara Enterprise – but we will continue to provide support for customers on Payara Community. 

When do new features get added to Payara Platform Enterprise?

As a general rule, new features are first added to Payara Platform Community, where they are thoroughly tested and developed. Once a feature has stabilized and ready for mission critical production environments, it is moved to Payara Platform Enterprise.  Some features are only available in the Payara Platform Enterprise, added once stability is confirmed.

What is the Payara Enterprise versioning system? 

Payara Enterprise uses a three component semantic-like versioning convention. 

Major Version Number . Minor Version Number . Patch Version Number 

Payara Platform 5.20.0 = Major Version 5, Minor Version 20, Patch 0 

Major Version numbers will start from 5 (the current major version of Payara Platform) and only increment by 1 when a new major version (E.g Payara 6) is released. Fundamental changes (e.g. Javax to Jakarta breaking change) will only be released in Major Versions.  

Customers should expect changes to their applications and configuration scripts to move to a Major version. 

Minor Version numbers will start from 20 (the year that Payara Enterprise and Community versions diverge) and increment by 1 quarterly. These version changes will introduce significant features once the features have been thoroughly tested in the Community version and are deemed stable.  

Features introduced during a minor version change are backwards compatible with previous minor releases . 

You should not need to change applications and configuration scripts to move to a minor version. 

Patch Version numbers will start from 0 and as a minimum increment monthly. These version changes will introduce bug fixes and patches. The Patch Version number will reset to 0 on a Minor Version release. 

If you receive a hot fix, a customer-specific version of the software adds an additional 4th level number to reflect the hot fix.  

There is no need to change applications and configuration scripts to move to a patch version. 

How do I calculate how many servers I need to buy?

Payara Enterprise support services pricing is calculated per core and 12 month annual subscriptions are available – contact our Sales Team for more information .

What are your long term plans for Payara Enterprise?

We have a 10-Year Payara Software Lifecycle policy in place, which ensures longevity of your investment in Payara Platform Enterprise. It provides you with 10 years of support and a well-defined lifecycle model, maintaining stability of your Payara Server or Payara Micro production environment.

Payara has a number of long-term Enterprise customers. Large, multinational and well-funded organisations including BMW Group, iTAC and Rakuten decided to invest in Payara Platform Enterprise to use it in their complex production environments. If you would like to find out more or request some customer references, please contact us directly.

How do I upgrade to the latest Payara Server Enterprise or Payara Micro Enterprise Edition? 

There are two valid methods of fully upgrading to a new release of Payara Server, described in our documentation here. To upgrade Payara Micro, you just need a new version of the Payara Micro JAR file – no installation required.

OpenJDK Support

What is Zulu Enterprise?

Zulu Enterprise is a tested, certified build of OpenJDK that is compliant with the Java SE standard for Java SE 9, 8, and 7.

Do I have to use Zulu JDK with Payara Platform Enterprise?

No, you can use any other supported JDK with Payara Server and Payara Micro. However, if you buy Payara Enterprise, you can benefit from Payara’s partnership with Azul, providing you with access to Zulu Enterprise – Fully Supported Builds of OpenJDK – with Payara Server and Payara Micro, for no extra cost.

Is Payara bundling Zulu Enterprise with Payara Server?

The Zulu JDK will not be bundled in the same downloadable artefact, but Payara will make Zulu Enterprise available as a separate download for all Payara Enterprise customers.

As a Payara Enterprise customer, where do I download Zulu from?

Payara Customers with Payara Platform Enterprise subscriptions should download Zulu and Payara Server directly from Payara to be sure that they are getting all the latest security updates and fixes.

What Java versions does Payara support?

Private, updated builds of Java 7 will be available through Payara Platform Enterprise for the lifetime of Payara Server 4.x and updated builds of Java 8 will be available for the lifetime of Payara Server 5.x, so customers can plan for the future safely. Since access to Zulu Enterprise is one of Payara Platform Enterprise features, Enterprise customers will maximise their investment by downloading those builds from Payara’s repository.

Can I raise JDK tickets in the same way as Payara Server?

Yes, we provide full support for Zulu Enterprise backed by Azul support. Our Support Engineers will work with you and Azul support to resolve any JDK issues.

Can I use Zulu Enterprise on systems without Payara and get support?

No, support for Zulu Enterprise is only provided under your Payara Enterprise contract when used with Payara Platform Enterprise.

What is with the name Payara?

Payara is a bad-ass fish from Venezuela (just Google it) – we thought it was appropriate! It also means we can have some cool branding and swag 😉
